Solar Distributed Generation

In distributed solar generation systems, every generation unit is enabled to perform its main functions at the individual photovoltaic (PV) panel level rather than on a string or array of photovoltaic modules.

Microinverter

Microinverters are often used as an alternative to string inverters to perform the DC to AC power conversion at solar panel level in residential photovoltaic systems. A solar micro inverter helps maximize energy yield and mitigate problems related to

Power Optimizer

In architectures based on the use of solar power optimizers, the maximum power point tracking (MPPT) function is performed at the level of each photo-voltaic panel so they all operate at their maximum power point.  This results in an improved energy

Distributed Generation implementations

Two implementations are possible using either solar micro-inverters – fed by a single panel and directly connected to the AC grid – or by means of power optimizers – fed by a single panel in a string that performs the Maximum Peak Power Tracking (MPPT) with its output connected to feed a single inverter. 

The power rating for each unit is typically between 50 and 400 W and a data logger and internet gateway collects data from all the panels and inverters and sends this information to a local or remote monitoring and control access point with efficiency and reliability being key to a successful design.
